Scientists Create New Material That May Lead to Self-Healing Electronics

Scientists have developed a new type of material that could be used in the future to create self-healing electronics, such as smartphones, batteries, speakers, robotics, and others.

The new material, which doesn't have a name as of yet, is transparent, stretches up to 50 times its size, conducts ions to generate current, and stitches itself together in about a day, at room temperature, after being completely torn apart.

New material repairs itself in about a day

The new material is the work of Ph.D. Chao Wang, from the University of California, Riverside, who's been working on it for the past two years.

Previous research on this material has been published here and here, and the material has been called an artifical muscle, albeit is not intended for medical applications. The reason it's been called this is because it responds and moves to electrical signals, just like a real muscle.

At the chemical level, this material is a combination between an ionic salt and a stretchable polymer (vinylidene fluoride-co-hexafluoropropylene), which stays together thanks to fluid-like type of bond called an ion-dipole interaction.

Researcher initially wanted to make a self-healing battery

Wang says he started working on this material being inspired by X-Men character Wolverine, wanting to create a self-healing lithium ion battery that could repair itself when dropped and damaged.

His research advanced as he realized the material is highly transparent and could be used for other purposes, such as a smartphone's screen.

Wang's research will take this type of material to the next level, allowing manufacturers to employ it for more than covers. Currently, Wang's team is testing the material in high-humidity environments, wanting to see how water affects the self-repair operations.

The scientist showed his most recent studies this past week at a meeting of the American Chemical Society. Below is a video of Dr. Wang presenting his work and answering questions from the press.
